EXECUTIVE SUMMARY
This document constitutes the Certification Report for the certification file of the product openNAC
Enterprise v1.2.
OpenNAC Enterprise is a solution that provides Network Access Control for corporate networks
(LAN/WAN) by authenticating, authorizing and auditing accesses to the network. It is a software
solution and its components execute on general purpose computing hardware, always in a
virtualized environment, which is provided by the Operational Environment.
Developer/manufacturer: Opencloud Factory S.L.
Sponsor: Opencloud Factory S.L..
Certification Body: Centro Criptológico Nacional (CCN) del Centro Nacional de Inteligencia (CNI).
ITSEF: Epoche & Espri S.L.U..
Protection Profile: None.
Evaluation Level: Common Criteria v3.1 R5 EAL2.
Evaluation end date: 20/05/2019.
All the assurance components required by the evaluation level EAL2 have been assigned a “PASS”
verdict. Consequently, the laboratory Epoche & Espri S.L.U. assigns the “PASS” VERDICT to the
whole evaluation due all the evaluator actions are satisfied for the EAL2, as defined by the Common
Criteria v3.1 R5 and the CEM v3.1 R5.
Considering the obtained evidences during the instruction of the certification request of the
product openNAC Enterprise v1.2, a positive resolution is proposed.
TOE SUMMARY
As opposed to specific network equipment, openNAC is a software product, so it does not have the
capability to perform the control of network accesses itself. Instead, it relies on an environment
configuration where the network devices such as switches are configured to "talk" to the TOE by
sending RADIUS requests. When a client (i.e. user computer) requests access to the network, the
network device in the environment send RADIUS requests to the TOE. Upon receiving these
requests, the TOE performs access control policy evaluation tasks and determines if it grants or
denies access to the network for the client, providing such information in the RADIUS response.
Then, the network device enforces the access control on the network, by granting or denying access
to the client based on the RADIUS response returned by the TOE.
The access control of user and devices to the network resources TOE is based on policies, these
policies indicate the rules for granting or denying access of users to the network. To establish and
4/12
https://oc.ccn.cni.es
organismo.certificacion@cni.es
configure the access control policies, the TOE provides an interface in the form of a REST API, that
can be used directly or through a web portal, which is included in the set of services contained in
the TOE virtual machine. Through this interface, an administrator can authenticate in order to
establish policies, register or edit user or devices, among other administrative tasks. This interface
also allows to view the audit data generated by the TOE in response to management or security
events.
For regular users, those that try to access to resources in the local area network without being
involved in management functions, the use of the TOE is transparent. They operate normally
without any direct interaction with the TOE, and the configured network devices enforce the access
control for them, in collaboration with the TOE, in charge of policy evaluation.
The TOE is deployed as a virtual machine running on a general purpose computer connected to the
local area network. Once the operating environment is properly prepared, including the
configuration of the network devices in a way that all authentication and authorization requests are
set to the TOE, the TSF can be deployed. The TOE major security features are the following:
• Audit generation. The TOE generates audit data related to management events
(administrative actions), and events related to network access, where access control policy
to the network is enforced.
• Management functions: via the web interface, it is possible for administrators to manage of
user, devices, policies, etc. Audit data can be consulted through this interface as well.
• Network Access Control for users and devices to networks. The TOE attends authorization
and authentication requests from the configured network devices in the operational
environment that result in the evaluation of the access control policies and it providing
responses to the devices that they will use to grant or deny access.
• Role-based access control to management functions. The different management functions,
provided via web interface, are available with a different level of permissions depending on
the user roles. Different roles are defined in the TOE and they have different sets of
permissions for performing management actions. Assignment of roles to users is possible via
the web interface.
 Protection of communications. The web interface (REST API) communications, used for TOE
management, are protected since HTTPS is used in the TOE evaluated configuration.

SECURITY POLICIES
The use of the product openNAC Enterprise v1.2 shall implement a set of security policies assuring
the fulfilment of different standards and security demands.
The detail of these policies is documented in [ST], chapter 3.4 (Organizational security policies).
ASSUMPTIONS AND OPERATIONAL ENVIRONMENT
The assumptions detailed in [ST], chapter 3.5 (Assumptions) are constraints to the conditions used
to assure the security properties and functionalities compiled by the security target. These
assumptions have been applied during the evaluation in order to determine if the identified
vulnerabilities can be exploited.
In order to assure the secure use of the TOE, it is necessary to start from these assumptions for its
operational environment. If this is not possible and any of them could not be assumed, it would not
be possible to assure the secure operation of the TOE.
CLARIFICATIONS ON NON-COVERED THREATS

RECOGNITION AGREEMENTS
In order to avoid multiple certification of the same product in different countries a mutual
recognition of IT security certificates - as far as such certificates are based on ITSEC or CC - under
certain conditions was agreed.
European Recognition of ITSEC/CC – Certificates (SOGIS-MRA)
The SOGIS-Mutual Recognition Agreement (SOGIS-MRA) Version 3 became effective in April 2010. It
defines the recognition of certificates for IT-Products at a basic recognition level and, in addition, at
higher recognition levels for IT-Products related to certain SOGIS Technical Domains only.
The basic recognition level includes Common Criteria (CC) Evaluation Assurance Levels EAL 1 to EAL
4 and ITSEC Evaluation Assurance Levels E1 to E3 (basic). For "Smartcards and similar devices" a
SOGIS Technical Domain is in place. For "HW Devices with Security Boxes" a SOGIS Technical
Domains is in place, too. In addition, certificates issued for Protection Profiles based on Common
Criteria are part of the recognition agreement.
The new agreement has been signed by the national bodies of Austria, Finland, France, Germany,
Italy, The Netherlands, Norway, Spain, Sweden and the United Kingdom. The current list of
signatory nations and approved certification schemes, details on recognition, and the history of the
agreement can be seen on the website at https://www.sogis.org.
The SOGIS-MRA logo printed on the certificate indicates that it is recognized under the terms of this
agreement by the nations listed above.
The certificate of this TOE is recognized under SOGIS-MRA for all assurance components selected.
International Recognition of CC – Certificates (CCRA)
The international arrangement on the mutual recognition of certificates based on the CC (Common
Criteria Recognition Arrangement, CCRA-2014) has been ratified on 08 September 2014. It covers
CC certificates based on collaborative Protection Profiles (cPP) (exact use), CC certificates based on
assurance components up to and including EAL 2 or the assurance family Flaw Remediation
(ALC_FLR) and CC certificates for Protection Profiles and for collaborative Protection Profiles (cPP).
The CCRA-2014 replaces the old CCRA signed in May 2000 (CCRA-2000). Certificates based on CCRA-
2000, issued before 08 September 2014 are still under recognition according to the rules of CCRA-
2000. For on 08 September 2014 ongoing certification procedures and for Assurance Continuity
(maintenance and re-certification)of old certificates a transition period on the recognition of
certificates according to the rules of CCRA-2000 (i.e. assurance components up to and including EAL
4 or the assurance family Flaw Remediation (ALC_FLR)) is defined until 08 September 2017.
